Hi all, just a quick question on injectors I couldn't find the answer to if you don't mind.

I have a 2014 103B softail with the stock 46mm cable actuated induction module with 3.91 injectors in it but was looking to follow a couple of others and look to step up a notch thinking I may look to a 110 drop in at some point later.

So, stock 46mm I believe can be bored to 50? but what about injectors? Injectors, there seem to be quite a few new take off's 27685-11A FBW induction modules with white band injectors knocking around but the injectors seem to be the Weber IPW162 white bands with no HD number.

Which is the 4.35 injector to go for? I understand there have been a couple of different part numbers with the 276709-01B being what's on the latest 103 softail and tourers but what are/were the differences and which ones to go for? I imagine 6 hole is better than 4 is better than 3 but have no idea which is which, or how to spot them.

cheers

 

mmm ok, the white bands seem to have different connectors to the 27709-06A 3.91's so there's the first problem with that idea

 

Anyone?

Apart from the 4.35 being EV1 plugs, are the dimensions the same to replace a 3.91 or would it need a different fuel runner - or should I look at the 4.9, are those the same size?

Apart from the older brown 4.35 that did have problems, does the number of holes and 8º vs 25º make any difference?

cheers

 

They are longer. You can get an extension but I don't like how they work out. They seem to not hold the injector very tight in place.

Thanks Jason, and for the links. So cheap take-offs are not looking as good as I thought they might

The 3.91's are running in high 80%'s so maybe best to leave putting 5.3's in until I get around to going higher cubes. I can always start buying bits now
